I am aware that water has beail introduced inw ear-stings by means atpipe-coils cast in tfiem, a-ml that suck castings with coils ofwatLr-pipe have fies used to cool certain parts of furnaces; and I donot claim this.

extending inward toward the lining of the same,said spaces being fitted.with iron linings or boxes and provided with spray-pipes for cooling thefurnace, as describeLL DANIEL N, JONES.
